~x-ai/grok-latest → A (2:1)

A adds real pairing logic (established-component bridges before isolate–isolate, then rank-adjacent zip once connected) plus targeted tests in pair.rs, improving core ranking behavior. B mostly splits/moves canonicalize helpers, strips @ from wire/storage, and propagates optional naked delegates across many call sites—valuable API hygiene, but more contract/refactor churn than new lasting capability.
